IMPROVED MEANS FOR WORKING SHIPS PUMPS.

Specieation forming part of Letters Patent No. 55,377, dated June 5, 1866.

To all whom it may concern:

Be it known that I, LEBBEUs SIMKINs, of the city of Brooklyn, county ot' Kings, State ofNew York, have invented a new and useful Improvementin Ships Pumps; andI do hereby declare that the following is a full, clear, and exact description thereof', which will enable others skilled in the art to make and use the same, reference being had to the accompanying drawings, forming part of this speciiication, in which- Figure l represents a plan or top view of this invention. Fig. 2 is a longitudinal vertical section ofthe same. Fig.3 is a transverse section of the same.

Similar letters of reference indicate corresponding parts.

This invention relates to ashipspump which connects by suitable gear-wheels and shafts with the capstan in such a manner that motion can be imparted to the plunger of the pump by turning the capstan, and the operation ofthe pump is materially facilitated. The gearing which serves to transmit mot-ion from the capstan to the pump is so arranged that the capstan and the pump can be readily thrown in or out of gear, and that the pump can be operated in the usual manner, it it should be desirable.

A represents a ships pump of any suitable construction. The plunger-rod B of this pump is guided in a suitable bracket, O, and it connects by a pitrnan, D, with a crank, F. A

bevel-pinion, G, mounted at or near the lower end of this arbor, gears in a bevel-wheel, H, which is secured to a horizontal shaft, I, and another bevel-pinion, J, mounted on the shaft I, gears iu av large bevel-wheel, K, on the vertical arhor L.

The shaft I has its hearing at one end, near the pinion J, in a lever, M, which is hinged to the under part of the deck or to any convenient portion of the vessel, and from which eX- tends a rod, N,up through a rnortise in the deck, so that'it can be fastened by passing through it a pin, a. (See Fig. 3.) By withdrawing this pin the lever M is made to sink down and the pinion J is thrown out ot' gear with the bevel-wheel K. r

The arbor L is secured to the barrel ot the capstan O, so that by turning said capstan the desired reciprocating motion is imparted to the plunger of the pump, provided the pinion J is not thrown out of gear with the wheel K.

By this arrangementtheoperation of a ships pump is rendered easy. A large number of men can be made to turn the capstan, and no great exertion is required from each individual to impart to the plunger the requisite speed. By throwing the pinion J out of gearwith the wheel K the capstan is disconnected from the pump, and it can be usedin the ordinary manner; and, if desired, the pump may also be so arranged that it can be readily disconnected from the gearing and made to operate in the usual manner.

What I claim as new, and desire to secure by Letters Patent, is-

The arrangement of a suitable connection, such as the shafts F F I L and bevel-wheels H J K, or any other equivalent means, in cornbination with the pumpA and capstan O, constructed and operating substantially as and for the purpose described.

The above specification ot' my invention signed by me this 26th day of March, 1866.
